This release adds development files and autotool examples for C/Lua modules or stand-alone tools for dnsjit.

Packages are available at: https://dev.dns-oarc.net/packages/

In examples/ you'll now also find:

  • modules/input-example
    This input example is based on dnsjit.input.zero which was a testing modules during the early days of dnsjit.
    It's a C module that generates empty objects for the receiver.

  • modules/filter-example:
    This filter example is C module that counts the number of objects passed to it before sending it to the receiver.

  • modules/output-example:
    This output example is based on dnsjit.output.null which was a testing modules during the early days of dnsjit.
    It's a C module that will just discard objects it receives.

  • modules/lib-example:
    This example Lua module takes two core_timespec_t C objects and gives the duration between them as a string.

  • stand-alone-tool:
    This example is based on test_pcap_read.lua and test_throughput.lua which was previous located in examples/.
    There are two installable Lua programs and shows how to depend on a dnsjit version, depend on specific dnsjit modules and how to run tests using make test.

All these examples can easily be copied and renamed to build and distribute your own dnsjit modules and tools, using autotool for configure, make and make install.

Development files will also be installed, or can be installed via dnsjit-dev/dnsjit-devel packages. All C headers have been prefixed with dnsjit/ (for example #include <dnsjit/version.h>).

Thanks to this new setup, the module output.dnssim has been moved out from dnsjit's repository and placed in DNS shotgun's: https://gitlab.nic.cz/knot/shotgun/-/tree/master/replay/dnssim
This will help CZ.NIC to maintain and release both the module and tool at the same time.

New modules:

  • Added input.zpcap, module for reading LZ4/ZSTD compressed PCAPs
  • Added core.loader, module for loading C modules using LuaJIT's ffi interface and package.cpath
  • Added core.file with core_file_exists(), a C function to check if a file exists

Other changes:

  • Add <dnsjit/version.h> for DNSJIT_MAJOR_VERSION, DNSJIT_MINOR_VERSION, DNSJIT_PATCH_VERSION
  • dnsjit: Remove version print on start
  • dnsjit.input.zero: Will require("example.input.zero") for backwards compatibility
  • dnsjit.output.null: Will require("example.output.null") for backwards compatibility
  • core/timespec: Add :max_init(), return a new object with maximum values set for seconds and nanoseconds.
  • output/pcap:
    • Update open() man-page, indicate usage of pcap_dump_open()
    • Add have_errors() to check for write errors during/after dumping
  • input.fpcap: Add fadvise_sequential() to advise sequential read of the file
  • examples/dumpdns.lua: Add support for dumping compressed PCAPs

Bugfixes:

  • lib/getopt: Fix short options, error if length is not 1
  • core/timespec: Fix typo in struct documentation
